## Title
Gun sight and method for hitting a moving target

## Abstract

A method and apparatus for configured to be attached to a gunbarrel of a firearm helping to aim at a moving target. The gun sight includes different-sized sight indicators including a first sight indicator located to be closer to the gunbarrel, and a second sight indicator, smaller than the first sight indicator and located to be further from the gunbarrel, both along a first direction that extends from the gunbarrel. In some embodiments use a plurality of different-sized of sight indicators along each of a plurality of directions for tracking moving targets approximately in those directions, for helping determine the amount of lead (the angle between the gunbarrel and the line to the target) used when shooting. Some embodiments use indicators, such as printed or embossed lines, icons, or tinted shapes, on a transparent substrate, while others use a wire-like structure formed with the indicators. Some embodiments use an anti-reflective coating.

## Background
FIELD OF THE INVENTION
This invention relates to the field of firearm aiming, and more specifically to a method and apparatus for assisting aiming a gun to appropriately lead a moving target.
BACKGROUND OF THE INVENTION
Firearms have been used by people for centuries. Aiming aids such as sights, crosshairs, or telescopes have been added to various firearms to assist the shooter in pointing the gun at a target.
Since the projectiles shot from a gun have a limited velocity, they drop in a curve (typically an asymmetric parabolic curve). Thus, when shooting at a stationary target, the sight on a gun will be set to aim the barrel (i.e., a straight line extending from the axis of the barrel) above the target by an amount that compensates for the drop in the projectile as it travels the distance to the target.
Moving targets present a more difficult problem. Since the target will have moved some distance left, right, up, or down (and perhaps closer or further away) between the time the projectile is launched and the time the projectile reaches the target, the barrel will have to be pointed to lead the target in its direction of travel. A closer target will require a smaller amount of lead angle than a target further away. A slower target will require a smaller amount of lead than a faster target. With prior-art sights, it has been quite difficult to estimate the size of lead angle to provide.
U.S. Pat. No. 4,112,583, “GUN LEAD SIGHT” issued Sep. 12, 1978 to Castilla describes a lead sight with numbers, corresponding to the numbered shooting positions on a standard skeet range, printed on a transversely extended transparent member mounted by a strap above gun barrels toward the muzzle end. “High” and “Low”, also imprinted on the transparent member, correspond to the high house and the low house from which the clay pigeons are released. Such a lead sight purportedly helps the beginner in skeet shooting to lead the skeet clay “bird” properly and helps the experienced shooter having a problem with one or more positions. While perhaps useful for skeet where the target is always at a fixed distance, such a gun sight is much less useful for hunting real game where the target is at various ranges and differing speeds.
U.S. Pat. No. 1,421,553, “GUN SIGHT” issued Jul. 4, 1922 to Pohl describes a lead sight useful for a shotgun, whereby the target object may be sighted while in motion and the shot fired at a lead angle in advance of the target such that the distance traveled by the target during the flight of the shot after discharge of the gun is compensated by the lead angle of the barrel when fired. This sight is formed by a transversely mounted bar having a plurality of bore-hole sight openings formed at different angles (each formed at a different radial angle), the radius center point corresponding to the position of the hunter's eye in sighting along the center ridge. The sight openings are each the same size and shape, other than being at differing angles. The marksman is left with the duty to judge the distance to the object and its speed (e.g., that a bird is flying 350 feet away and at a speed that would need a sight line about eight feet in front of the bird). This would be a difficult judgment task for a hunter in the field hunting real game where the target is at various ranges and differing speeds.
U.S. Pat. No. 3,178,824, “SHOT GUN SIGHTING DEVICE” issued Feb. 16, 1961 to Callihoe describes an elliptical shotgun lead sight with radially extending lines and different sized concentric ellipses. This device also leaves the marksman with the problem of judging distance to the object and its speed.
What is needed is a sight better configured to assist the shooter in estimating the size of lead angle to provide for a given moving target, and to help automatically point the barrel of the gun at the appropriate angle to the target.
SUMMARY OF THE INVENTION
The present invention provides an aiming mechanism and method that provide a plurality of different-sized target alignment indicia extending out in at least one direction from the barrel of a gun, wherein larger-sized artifacts, used to align to closer targets, are placed closer to the barrel of the gun since those closer objects require less leading. By matching the size of the artifact to the apparent size of the moving target, the distance to the target can be compensated for, and the proper amount of lead (the angle for pointing the barrel relative to the target) can be provided for targets of any given distance. By providing different customized sights for targets having different inherent speeds, the appropriate amount of lead can be matched to the speed of the target. Thus, a sight used for hunting pheasants can be customized such that the various different sized artifacts used to estimate distance to the pheasant target can be spaced apart by an amount that also takes into account the average flying speed of a pheasant. Further, a sight used for hunting fast-flying ducks can be customized such that the various different sized artifacts used to estimate distance to the duck target can be spaced apart by an amount that also takes into account the average flying speed of a fast-flying duck.
In some embodiments, the sighting indicia are icons representing the outline of a particular type of game. The icons located closest to the gun barrel are of a large size, which when aligned with a target that is close to the shooter will be of the same size as the apparent size of the target. The icons located furthest from the gun barrel are of a small size, which when aligned with a target that is far to the shooter will be of the same size as the apparent size of that target. The icons located between those located closest to the gun barrel and those located furthest from the barrel are of an intermediate size, which when aligned with a target that is intermediate in distance from the shooter will be of the same size as the apparent size of that target.
Various embodiments provide a method and apparatus configured to be attached to a gunbarrel of a firearm and having a plurality of different-sized sight indicators including a first sight indicator located to be closer to the gunbarrel, and a second sight indicator, smaller than the first sight indicator and located to be further from the gunbarrel, both along a first direction that extends from the gunbarrel. In some embodiments, a series of different-sized sight indicators is provided in each or a plurality of directions for tracking moving targets moving approximately in those directions, for helping the shooter determine the amount of lead (the angle between the gunbarrel and the line to the moving target) to use when shooting such that the moving bullet or pellets intersect with the moving target. Some embodiments use indicators, such as printed or embossed lines, icons, or tinted shapes, supported by a transparent substrate, such that the shooter matches the apparent size of the target with an appropriate sight indicator matching that size and along a line that matches the direction (e.g., of flight) of the target's movement. Other embodiments use a substantially open structure (e.g., formed from wire, thin metal strips, low-aspect-ratio cast plastic rods or strip shapes) with the indicators as shapes of the structure. Some embodiments use an anti-reflective coating. In some embodiments of the invention the sighting indicators or elements are fixed on a frame, while in other embodiments, they are adjustable.

DESCRIPTION OF PREFERRED EMBODIMENTS
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
The leading digit(s) of reference numbers appearing in the Figures generally corresponds to the Figure number in which that component is first introduced, such that the same reference number is used throughout to refer to an identical component which appears in multiple Figures. The same reference number or label may refer to signals and connections, and the actual meaning will be clear from its use in the context of the description.
The gun sight of the present invention has been developed to assist shooters in determining the appropriate lead when shooting a moving target. The invention provides a series of sight indicators or sight openings, as will be referred to in the rest of this description, which are, in some embodiments, applied to a transparent material and attached to a gun barrel. The transparent material used allows the shooter to see through the sight indicators to his or her intended target. These sight openings are placed in descending order from largest to smallest starting at the gun barrel and moving outward at multiple angles. There is a direct correlation between the size of the target and the size of the appropriate sight opening selected to make the correct lead necessary to hit the intended target. Closer targets appear larger and require less lead when shooting therefore the larger sight opening is selected. Distant targets appear smaller and require more lead when shooting therefore a smaller sight opening is selected. These sight openings can be made of a many shapes depending on the shooters preference. For example; simple shapes such as circles, ovals or crosshairs can be used with directional indicators for sighting targets. Other shapes such as outline drawings of the intended target can also be used. This gun sight can be used for a variety of shooting sports and be comprised of many shapes and sizes depending on the intended use. Some of these shooting sports include; waterfowl hunting, upland game hunting, sporting clays, trap shooting and skeet. In addition to shooting sports that require a lead for moving targets a gun sight has also been developed for stationary targets as well. This gun sight uses the same concept of descending sight openings. The closer the stationary target is the larger it will appear therefore the larger sight opening is used. Consequently distant targets will appear smaller and a smaller sight opening is used.
Using the Gun Sight:
The fundamental purpose of the gun sight is to help the shooter anticipate the appropriate lead of a moving target while staying focused on the intended target throughout the shot. Shooting moving targets can present many challenges to shooters because of the complex variables involved. When shooting a moving target the shooter must anticipate the appropriate lead needed to hit the target and at the same time keep the gun barrel moving in the same direction as the intended target while maintaining the constant lead determined. The most common mistake shooters make when shooting moving targets is shooting behind the intended target. This can happen for a variety of reasons as follows; the shooter under estimates the correct lead, the shooter stops the gun barrel when firing the shot, the shooter doesn't follow the same line of flight as the intended target, the shooter does what is called flock shooting or the shooter tries to aim at the target. Aiming is one of the most common mistakes of all shooters. Aiming seems to be the most natural thing to do when trying to hit a target. Most shotguns are equipped with a small bead or a more elaborate glowing sight at the end of the barrel. The intended use of these sights is to give the shooter a quick reference point to where the end of the barrel is when shooting. This can be helpful when trying to judge the lead ahead of the moving target. The problem is that most shooters aim down the barrel and try to push the gun ahead of the target using these sights as a guide. This usually results in the shooter chasing the target and never getting out ahead of the intended target. The unique design of this gun sight takes away most of the variables mentioned above and allows the shooter to do what comes natural to them. This gun sight makes it possible for the shooter to aim through the selected sight opening and stay focused on the intended target throughout the shot. Once a sight opening is selected the gun barrel will automatically move ahead of the target at the anticipated lead. In addition the barrel will follow the same flight pattern as the intended target as long as the shooter stays focused on the target and keeps it in the sight opening throughout the shot.
The Lead:
Determining the appropriate lead is often a matter of trial and error. Many variables come into play when trying to judge the right lead for a moving target. Factors that contribute to the process include target speed, direction of target, distance from shooter, wind speed, and ammunition (i.e., which contribute to the inertia and initial speed of the projectile). It can be difficult to correctly anticipate the effects these variables will have each time you shoot. Therefore the shooter must use past experience to help judge the correct lead for a given target.
The present gun sight provides a shooter a quick reference point to start from, and a more consistent success rate once the appropriate lead or sight opening is determined.
The following scenario will help illustrate how a lead is determined. For example, when duck hunting, a common lead is said to be three feet. This is a very difficult concept for most hunters because three feet can mean many things to different shooters, not to mention that it says nothing about the distance to or speed of the target. Three feet is usually used as a good starting point. Often times what happens is that a hunter will hold the gun at what they guess to be three feet ahead of the given target and pull the trigger. The result is usually a miss because no one told them to keep the gun moving ahead of the duck throughout the shot. By using the present gun sight, a hunter can select a sight opening starting with the largest opening closest to the barrel for less lead and work their way out using smaller sight openings for more lead until the correct sight opening (i.e., the sight indicator that matches the apparent size of the target) is determined. Once the correct sight opening is found for a target traveling at a given speed and distance, it is possible for the hunter to quickly aim and shoot, usually resulting in a better success rate.
The shooter must go through the previously mentioned process every time one of these variables changes. For instance, if a duck traveling at the same distance comes from the opposite direction and now is fighting a head wind, this will likely slow down the speed of the duck and less lead may be necessary. Therefore the shooter may have to select a larger opening for less lead in order to hit the intended target.
Overhead Shooting:
When shooting at moving targets overhead or targets coming towards the hunter the most common mistake is trying to shoot as the object approaches. This is a difficult shot because you usually have to cover the target with the gun and guess at the lead. Often times the hunter will only have one shot at this position because the target will be long gone if the hunter tries to turn and shoot again. This usually results in a missed shot and the hunter runs the risk of falling over backwards or even falling in the water, if hunting from a boat. The best way to hit this target is to turn around and wait for it to pass overhead. This way the hunter can keep the intended target in view at all times and better anticipate the lead, plus the hunter can usually get off a second shot in this position if needed. This gun sight has been specially designed to give the hunter the maximum advantage when shooting highflying targets that require an extended lead. The same basic principles come into play when shooting at targets overhead. The hunter simply selects the appropriate sight opening and keeps the target in the opening throughout the shot.
Straight Away Shooting:
Straight away shots are often the most frustrating because the shooter often shoots over the intended target. The target can be hit by holding the gun barrel just over the target at close range, but this requires the shooter to cover the target before shooting. As the target moves away from the shooter it is generally moving in a downward motion. This requires the shooter hold just below the target. In effect the hunter is anticipating the flight pattern of the target and creating a lead. This gun sight allows the shooter to adjust the lead by selecting the correct sight opening. The farther away the target is from the shooter the smaller the sight opening and the greater the lead.
FIG. 1 shows a front view of a gun sight 100 according to one embodiment of the invention. In some embodiments, gun sight 100 is made of a clear substrate 110, such as a plastic such as Lexan®, or hardened glass, or other suitable substantially clear, strong, resilient material. Substrate 110 can be (in various embodiments) water-clear, or tinted some color or shade of grey. Substrate 110 has a pattern of sight indicators that are (in various embodiments) printed, painted, stained, engraved, embossed, burned, formed by a focused laser, or otherwise formed on or in substrate 110. These sight indicators can be opaque, or translucent or transparent, and/or tinted a different color or shade of grey. The sized sight indicators (such as 142, 143, or 145) can be indicated as outlines (as the lines shown in FIG. 1), or as solid shapes (such as a tinted oval filled with a solid or varying color). Thus, the lines shown can be ink, paint, stain, color, etched metal lines, indentations, grooves, bubbles, opacities, shading, tinting, differences in index of refraction, or other visible means formed within and/or on the surface of substrate 110. The term “indicia on substrate 110” as used herein thus shall include any such indicators or indicia on the surface and/or within the substrate between the front and back surfaces.
Each group of sight indicators (for example, group 140, which includes sight indicators 142, 143, and 145, and optional line 141 and arrowhead 144) is intended for targets moving in a certain direction. In the case of group 140, this is a right-to-left direction. In the embodiment of gun sight 100, each sight indicator is a generic geometric shape, such as an oval, which can be used for a wide variety of targets such as clay targets, ducks, or pheasants. For far-away targets, the apparent size of the target will be relatively small, and the smallest sight indicator (i.e., oval 142) will most closely match the apparent size of the target as viewed through the gun sight 100. When the user aligns sight indicator 142 with the target (whose apparent size, when viewed through gun sight 100, most closely matches the size of sight indicator 142) that is moving right-to-left, the gunbarrel 93 will be pointed in a left-pointing direction that leads the target by a substantial amount, thus allowing the projectile and the target more time to reach the point of impact. If the target is much closer to the user, it will appear much larger, and will have an apparent size, when viewed through gun sight 100, that most closely matches the size of sight indicator 144. When the user aligns sight indicator 144 with this closer target that is moving right-to-left, the gunbarrel 93 will be pointed in a left-pointing direction that leads the target by a small amount, thus allowing the projectile and the target less time to reach the point of impact. Sight indicator 143 is used for targets at an intermediate range.
The other groups if sight indicators are used for targets moving in other directions. Each group will typically have one or more sight (usually two or three) sight indicators, and optionally a line and arrowhead. Group 120, consisting of sight indicators 122, 123, and 125, line 121, and arrowhead 124, would typically be used for overhead targets flying straight away from the shooter.
Group 130, consisting of sight indicators 132, 133, and 135, line 131, and arrowhead 134, would typically be used for overhead targets flying away and right-to-left from the shooter. Group 150, consisting of sight indicators 152 and 155, line 151, and arrowhead 154, would typically be used for just-flushed targets flying upwards and right-to-left from the shooter.
Group 180, consisting of sight indicators 182, 183, and 185, line 181, and arrowhead 184, would typically be used for overhead targets flying away and left-to-right from the shooter. Group 160, consisting of sight indicators 152 and 165, line 161, and arrowhead 164, would typically be used for just-flushed targets flying upwards and left-to-right from the shooter.
Finally, group 170, consisting of sight indicators 172, 173, and 175, line 171, and arrowhead 174, would typically be used for overhead targets flying left-to-right relative to the shooter.
In other embodiments, other numbers of groups of sight indicators are provided. In some embodiments, an anti-reflective coating is applied to the front or back of substrate 110, or both. In some embodiments, gun sight 100 is removably affixed to the distal end of gunbarrel 93 near the front bead 94 using a locking ring 192 that is attached to gunbarrel 93, and a matching clamping ring 190. In some embodiments, substrate 110 has a hole 2010 with a bottom flat, and is clamped between locking ring 195 (with its corresponding bottom flat 192) and matching clamping ring 190. In other embodiments, hole 2010 in substrate 110 has other shapes, such as a plain circle, or an over/under overlapping pair of circles to match an over/under double-barreled shotgun, or a side-by-side overlapping pair of circles to match an side-by-side double-barreled shotgun.
FIG. 2 shows a hunting system 200 with a hunter 90 holding a firearm 95 (such as a shotgun). Three possible targets, 97, 98, and 99, are shown at different distances. Firearm 95 can be a conventional shotgun having a sighting rib 92 and/or a sighting bead 94 formed or attached to gun barrel 93. In some embodiments, the surface plane of gun sight 100 (such as described for FIG. 1 above) is attached to be substantially perpendicular to the longitudinal axis of barrel 93. In other embodiments, the plane of gun sight 100 is tilted relative to the longitudinal axis of barrel 93, for example, having the top edge further from the butt end of the gun than the bottom edge (or, as shown in FIG. 2, having the left edge further away than the right edge), for example in order to reduce outward reflections that might spook the game that is being hunted, and/or reflections back to the shooter that interfere with the view of the game.
To illustrate the operation and use of the gun sight 100 as shown in FIG. 2, suppose a target, such as a flying duck, is moving in a substantially horizontal direction from right to left as viewed by the shooter 90. The shooter will choose to use sight indicator group 140, which includes (as shown in FIG. 1) sight indicators 142, 143, and 145, and optional line 141 and arrowhead 144, which is intended for targets moving in the right-to-left direction (as indicated by the direction of arrowhead 144). If the target is relatively far away, such as at position 99, the axis 80 of the barrel 93 should be pointed at a relatively large angle in front of the target 99. Since the target 99 will have a relatively small size due to its distance along line 89 from the shooter, the shooter will use the relatively small sight indicator 142 furthest from the barrel, and obtaining the large lead angle between line 89 and the line of the barrel axis 80. The target 99 initially at the position shown when the shot is taken will traverse distance 69, and the bullet or pellet projectile(s) will then intersect the target at point 79.
If the target is relatively close, such as at position 97, the axis 80 of the barrel 93 should be pointed at a relatively small angle in front of the target. Since the target 97 will have a relatively large apparent size due to its close distance along line 87 from the shooter, the shooter will use the relatively large sight indicator 145 closest to the barrel, and obtaining the small lead angle between line 87 and the line of the barrel axis 80. The target 97 initially at the position shown when the shot is taken will traverse distance 67, and the bullet or pellet projectile(s) will then intersect the target at point 77.
If the target is at an intermediate distance, such as at position 98, the axis 80 of the barrel 93 should be pointed at a intermediate angle in front of the target. Since the target 98 will have an intermediate apparent size due to its intermediate distance along line 88 from the shooter, the shooter will use the middle-sized sight indicator 143, and obtaining the intermediate lead angle between line 88 and the line of the barrel axis 80. The target 98 initially at the position shown when the shot is taken will traverse distance 68, and the bullet or pellet projectile(s) will then intersect the target at point 78.
FIG. 3 shows a view 300 as seen by the shooter with the sight indicator 143 superimposed over the target 98, as viewed through transparent substrate 110. The target 98 (e.g., a duck flying right to left) is moving in the direction of arrowhead 144, and thus the shooter selects indicator group 140 to use for aiming. If the target is moving in another direction, then one of the other groups 120, 130, 150, 160, 170, or 180 is selected, as appropriate.
FIG. 4 shows a front view of a gun sight 400. Rather than being visible indicia on a transparent substrate such as gunsight 100 of FIG. 1, gun sight 400 is formed from a thin solid material, such as one or more strips of metal (e.g., spring steel) formed or welded into the desired shape. In the embodiment shown, a flat horizontal strip 441 (i.e., a strip that is thin as viewed, but wider in a direction perpendicular to the sheet of the drawing) has a series of beads 432, 433, 435, a series of different-sized cross-wise strips 442, 443, and 445, and/or one or more arrowheads 439 and 444 affixed to its right side and used for targets moving right-to-left. Further, flat horizontal strip 441 has a series of beads 462, 463, and/or 465, a series of different-sized cross-wise strips 472, 473, and 475, and/or one or more arrowheads 469 and 474 affixed to its left side and used for targets moving left-to-right. In some embodiments, a clamp 402 and fastening mechanism 403 (such as a machine screw or bolt, and a nut or threaded lip) are provided to attach gun sight 400 to a gun barrel.
In other embodiments, the crossbars 442, 443, 445, 472, 473, and 475 are omitted, and the spacing between beads 462 and 463 is made smaller than the spacing between beads 463 and 465. Similarly, the spacing between beads 432 and 433 is made smaller than the spacing between beads 433 and 435. In some such embodiments, the arrowheads 444, 439, 474, and/or 469 are also omitted. In these embodiments, the spacings between beads are used as the size indicators used to align with the relative apparent size of the target 98 (or 97 or 99) of FIG. 7 to select the proper lead angle.
FIG. 5 is an enlarged breakaway view 500 of a duck 98 sighted through a portion of gun sight 400, wherein crossbar 443 is selected as the appropriately-sized sight indicator, since it approximately matches the apparent size of target 98.
FIG. 6 is a perspective view of a hunting system 600 that uses gun sight 400 attached to the gun barrel 93 of a firearm. Clamp 402 is shaped to accommodate the size and shape of gunbarrel 93 and sighting rib 92. In some embodiments, clamp 402 is flexible enough to allow sliding of the gun sight 400 over front sighting bead 94 of the gun. In the embodiment shown, gunsight 400 has a longitudinal cross section that is relatively long in the direction parallel to the axis of the gun barrel 93 to provide extra strength, but narrow as viewed by the shooter to reduce the amount of sight blocked by gunsight 400. In some embodiments, gunsight 400 is made of one or more folded and/or welded strips of metal, such as spring steel. In other embodiments, gun sight 400 is cast from metal and/or plastic material(s). In some embodiments, arrowheads 439, 444, 474, and 469 are solid, while in other embodiments, they are hollow in order to block less of the view.
FIG. 7 is a top view schematic 700 of the use of gun sight 400. The shooter's eye is at location 710 looking approximately along the barrel of gun 95. A distant target 99 moving right-to-left (downward in the figure) would be tracked and aligned to sight indicator 442 and/or bead 432 along line 89 and the trigger pulled.

FIG. 41 is front view of a gun sight design 4100, where substrate 4110 includes iconic representations of stationary game, such as turkeys. For this type of game, typically less than forty yards away, and thus having almost no projectile drop, gun sight 4100 is designed to help the shooter aim for the correct portion of the anatomy. In some embodiments, the size of each icon is different, and the icons are nested within one another. For game that is further away, the shooter must aim at a smaller angle from the top of the target (e.g., to hit the desired point on the neck), and thus the small icon 4122 is situated such that when aligned to a far away turkey target, the barrel of the gun is angled at a smaller angle from the top of the target than when icon 4123 is aligned to an intermediate distance turkey target. The barrel of the gun is angled still lower when icon 4125 is aligned to a nearby target.
FIG. 42 is front view of a gun sight design 4200 used for hunting deer, elk, and similar game. Gun sight 4200 helps the shooter compensate for bullet drop over distance. The numbers in quotation marks are printed (or otherwise formed) on substrate 4210 (as numbers, not necessarily having the quotation marks), and do not represent reference numbers of the Figure. A plurality of different-sized game icons, e.g., small icon 4220, intermediate-sized icon 4222, and large icon 4223 are provided for the hunter to align to the game to help judge distance to the game. Further (or alternatively), in some embodiments, a plurality of horizontal lines of different lengths are provided, such as short line 4215, and longer lines 4214, 4213, 4212, and 4211, corresponding respectively to distances of “200,” “150,” “100,” “75,” and “50” yards (or meters). The size of each of these lines can be used to help judge distance, and thus the amount of upward angle to provide to the gun barrel when shooting. When the distance has been judged, the bead 94 is aligned to the desired spot on the target (e.g., the heart) as if almost no projectile drop (i.e., as if the target were only 50 yards away). The barrel is then lifted by an amount corresponding to the distance just judged. For example, if the earlier procedure judged the distance to be 150 yards (or meters), the gun would be raised until the “150” line 4214 coincided with where the “50” mark 4211 was when the initial alignment was made, and the shot is taken. Alternatively, the target is aligned to one of the different-sized left-hand icons, and the gun is then moved horizontally at that level until the number of the vertical lines 4230 moved would align the gunbarrel to where the game is. This can be necessary since in some instances the barrel of the gun blocks the view to distant game, and the horizontal lines 4211-4215 allow the shooter to accurately determine how much rise to provide, and the vertical line 4230 help in moving the gun straight up for the first procedure described, or to determine how much side movement to use for the second procedure.
